For the first time since GE exists I had to renew my US passport. Entering the new data was simple and almost instant. The new one is already registered in the system and worked the first time out. I thought it could not be so easy, but it is. They asked for other passport information so I entered my Brazil data too. I do not know why they want that for sure, but an immigration officer standing by as I arrived this time said that the idea was to permit showing only the foreign passport for US departures at some future date. Maybe, but... Another kudo for the system on the passport update!
